Towards robust simulations of the galactic dynamo: a cross-code comparison between Eulerian and Lagrangian schemes
Mark Ivan Ugalino, Benedikt Diemer, Vadim A. Semenov +8
Galactic magnetic fields are thought to be seeded by microscopic processes such as the Biermann battery and are primarily amplified to observed microgauss strengths by dynamo proce…
Saturation Mechanism of Cosmic Ray Streaming Instabilities with a Shell Distribution
Mohamad Shalaby, Rouven Lemmerz, Christoph Pfrommer
Cosmic rays (CRs) drive galactic winds and regulate galaxy growth while contributing to heating the central cooling plasma in dense galaxy clusters, making the nonlinear saturation…
High-spectral-resolution Observations of the [S II] Emission-line Doublet in the Filamentary Nebula Surrounding NGC 1275
Benjamin Vigneron, Julie Hlavacek-Larrondo, Carter Lee Rhea +10
We analyze new high-spectral resolution SITELLE observations (R = = 7000) of the filamentary nebula surrounding NGC 1275, central galaxy of the Perseus cluster. We present h…
CRexit observed: probing cosmic ray transport in the circumgalactic medium with absorption line spectra
Matthias Weber, Timon Thomas, Christoph Pfrommer +1
Cosmic rays (CRs) likely provide dynamically important non-thermal pressure support in the circumgalactic medium (CGM), but how their transport physics shapes observable absorption…
A comparison of numerical schemes for driven subsonic MHD turbulence
Rüdiger Pakmor, Thomas Guillet, Rebekka Bieri +3
Turbulence is ubiquitous in astrophysical systems, and since most cosmic gas is ionised, it supports magnetic fields. In turbulent environments, these fields are rapidly amplified…
The PICO-Cluster Project: presenting the galaxy cluster sample and studying magnetic field growth, Faraday rotation and Braginskii heating
Thomas Berlok, Christoph Pfrommer, Ewald Puchwein +9
Galaxy clusters constitute a microcosm of the Universe and offer a unique laboratory for studying plasma astrophysics, encompassing processes such as cosmic-ray acceleration and no…
